Researchers in a certain country investigated how having daughters influences voting on women's issues by members of the federal government. The researchers use voting records of each member of the federal government to compute an index score, where higher scores indicate more favorable voting for women's rights. The researchers modeled the index score (y) as a function of the number of daughters (x) a voting member has. Data collected for the 422 members of the federal government last year were used to fit the straight-line model, E(y) = β0 + β1x.

(a) If it is true that having daughters influences voting on women's issues, will the sign of β1 be positive or negative? Explain.

step-by-step explanation:

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
